Field of the Invention The present invention relates to a press sleeve for press-treating a web material with a long wup width, and more particularly to an elastic sleeve for a press press formed of an elastic material in a cylindrical shape, a method of manufacturing the same, and a press roll using the same.

シユープレスは、 製紙工業の脱水プレス工程で用いられている。 シユープレス とは、 簡単に言えば、 走行方向に所定の幅を持つ加圧シユーを用いて弹性ベルト (スリーブ） を対向するプレスロール側に押しつけることにより、 広い幅の加圧 領域を形成し、 この加圧領域に加圧対象物であるウェブ材料 （湿紙） を通して加 圧処理 （脱水） を行なうものである。 通常のロールプレスは加圧対象物に線圧力 を加えるのに対し、 シユープレスでは加圧シユーが走行方向に所定の幅を持った め、 加圧対象物に面圧力を加えることができる。 このため、 シユープレスを用い た場合、 エップ幅を大きくすることができ、 処理性能を高めることができるとい う利点がある。  Shu press is used in the dewatering press process of the paper industry. In short, a press press is to form a wide pressurized area by pressing a flexible belt (sleeve) against an opposing press roll using a pressurizing press having a predetermined width in the running direction. Pressure processing (dehydration) is performed by passing a web material (wet paper), which is the object to be pressed, into the pressure area. A normal roll press applies a linear pressure to an object to be pressurized, while a shure press applies a surface pressure to the object to be pressurized because the pressurized shoe has a predetermined width in the running direction. For this reason, there is an advantage that the use of the shuppress allows the width of the epoxy to be increased and the processing performance to be improved.
なお、 脱水プレス以外にも、 製紙工業や磁気記録媒体製造工業等において、 紙 や磁気テープ等のウェブ材料のつや出しを行なうカレンダー用としても、 シユー プレスの使用が検討されている。  In addition to the dewatering press, the paper press industry and the magnetic recording medium manufacturing industry, etc. are also considering the use of a shure press for calendering web materials such as paper and magnetic tape.

In the figure, a press machine 100 is composed of a press roll 101 and a press roll 102 facing the press roll 101.
プレスロール 1 0 1は、 金属、 石、 合成ストーン、 セラミックス等の硬質材料 力 らなり、 高速回転する。 シユープレスロール 1 0 2は、 実質的に回転しない支 持軸 1 0 3と、 支持軸 1 0 3の上に载置された加圧シユー 1 0 4と、 支持軸 1 0 3の両端部に取付けられたスリーブ支持部材 1 0 5と、 支持軸 1 0 3および加圧 シユー 1 0 4を覆いスリープ支持部材 1 0 5によって端部が支持された弾性スリ ープ 1 0 6とを備えている。 弾性スリープ 1 0 6は、 シユープレスロール 1 0 2 の一端側からスリーブ支持部材 1 0 5の外周面に被せて引っ張り込みながら取り 付けられる。 スリープ支持部材 1 0 5はディスク状であり、 シユープレスロール 1 0 2の端面を構成している。  The press roll 101 is made of a hard material such as metal, stone, synthetic stone, and ceramics, and rotates at high speed. The press roll 102 includes a support shaft 103 that does not substantially rotate, a pressurizing shoe 104 mounted on the support shaft 103, and both ends of the support shaft 103. And a resilient sleeper 106 which covers the support shaft 103 and the pressurizing shoe 104 and whose end is supported by the sleep support member 105. I have. The elastic sleeve 106 is attached while being pulled from one end of the press roll 102 to the outer peripheral surface of the sleeve support member 105. The sleep supporting member 105 has a disk shape and forms an end face of the press roll 102.
スリーブ支持部材 1 0 5の内径部と支持軸 1 0 3との間にはベアリングが介在 していて、 スリーブ支持部材 1 0 5が支持軸 1 0 3に対して回転可能とされてい る。 加圧シユー 1 0 4は、 気圧、 油圧等の圧力手段により弾性スリーブ 1 0 6を 内側から外側に向けて加圧する。 加圧シユー 1 0 4と弾性スリーブ 1 0 6の内面 との間には潤滑油が供給され、 弾性スリーブ 1 0 6は、 加圧シユー 1 0 4の上を 滑りながらスリーブ支持部材 1 0 5とともに支持軸 1 0 3の周りを回転する。 弾 性スリーブ 1 0 6は、 気体および液体に対して非透過性の合成樹脂材料からなつ ている。 このような材料は、 例えばポリウレタンである。  A bearing is interposed between the inner diameter portion of the sleeve support member 105 and the support shaft 103, and the sleeve support member 105 is rotatable with respect to the support shaft 103. The pressurizing shoe 104 presses the elastic sleeve 106 from the inside to the outside by pressure means such as atmospheric pressure or hydraulic pressure. Lubricating oil is supplied between the pressurizing shoe 104 and the inner surface of the elastic sleeve 106, and the elastic sleeve 106 slides on the pressurizing shoe 104 together with the sleeve support member 105. Rotate around the support axis 103. The elastic sleeve 106 is made of a synthetic resin material that is impermeable to gas and liquid. Such a material is, for example, polyurethane.
弹性スリーブ 1 0 6とスリーブ支持部材 1 0 5との間は、 潤滑油を外部に漏ら さないように、 また、 シユープレスロール 1 0 2の内部の気密性を保つように、 しっかりとシールされ、 固定されている。 内部に圧力ガスが供給されるシユープ レスロール 1 0 2は、 弾性スリーブ 1◦ 6を膨らませた状態で運転される。 弾性 スリーブ 1 0 6とプレスロール 1 0 1との間には、 処理対象物である湿紙等のゥ エブ材料 1 0 7が通過する。 加圧シユー 1 0 4の表面は、 走行方向に所定の幅を 有し、 プレスロール 1 0 1の表面に対応した滑らかな凹状とされ τいる。 このた め、 プレスロール 1 0 1とシュ一プレスロール 1 0 2との間には、 広い幅の加圧 領域が形成され、 ウェブ材料 1 0 7は、 この加圧領域でプレスされる。 運転時において、 シユープレスロール 1 0 2の弾性スリーブ 1 0 6には、 圧縮 力、 引張り力等の複雑な力が作用する。 このため、 従来、 弾性スリープ 1 0 6は、 運転時に作用する力に対抗して強度と寸法を維持する必要性から、 弾性材料と基 布等の捕強材との複合材料により成形されていた。 Securely seal between the flexible sleeve 106 and the sleeve support member 105 to prevent leakage of lubricating oil to the outside and to maintain the airtightness of the inside of the press roll 102. Has been fixed. The press roll 102 to which the pressurized gas is supplied is operated with the elastic sleeve 1 · 6 expanded. Between the elastic sleeve 106 and the press roll 101, a web material 107 such as a wet paper to be processed passes. The surface of the pressurizing shoe 104 has a predetermined width in the running direction and has a smooth concave shape corresponding to the surface of the press roll 101. For this reason, a wide pressing area is formed between the press roll 101 and the press roll 102, and the web material 107 is pressed in this pressing area. During operation, a complex force such as a compressive force or a tensile force acts on the elastic sleeve 106 of the press roll 102. For this reason, the elastic sleep 106 was conventionally formed from a composite material of an elastic material and a reinforcing material such as a fabric, because it was necessary to maintain strength and dimensions against the force acting during operation. .
それにもかかわらず、 使用とともに、 弾性スリーブ 1 0 6には疲労による伸ぴ が生じ、 内部からの気圧も作用して、 径方向に徐々に膨れていくことが避けられ なかつた。 弾 1"生スリーブ 1 0 6が径方向に膨れると、 運転時に弾性スリーブ 1 0 6が煽り始め、 走行が不安定になって、 ウェブ材料の損傷や品質悪化の原因とな つたり、 弹性スリーブ 1 0 6に傷、 摩耗、 クラック等が発生する原因となったり するという問題があった。 発'明の開示  Nevertheless, with use, the elastic sleeve 106 was stretched due to fatigue, and due to the pressure from the inside, it was inevitable to gradually expand in the radial direction. When the bullet 1 "raw sleeve 106 expands in the radial direction, the elastic sleeve 106 starts to fly during operation, causing unstable running, which may cause damage to the web material or deterioration of the quality, or a flexible sleeve. There was a problem in 106 that it could cause scratches, wear, cracks, etc.
それゆえに、 この発明の目的は、 弾性スリーブの膨れを抑制することができ、 その結果として耐久性を向上させ、 走行安定性を長期間維持することのできるシ ユープ ス用弾性スリーブおよびその製造方法ならびにそれを用いたシユープレ スロールを提供することにある。  SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an elastic sleeve for a sleeve capable of suppressing swelling of the elastic sleeve, thereby improving durability and maintaining running stability for a long period of time, and a method of manufacturing the same.

The feature is that the inside diameter is gradually reduced from both ends to the center.
また、 この発明によるシユープレスロールは、 実質的に回転しない支持軸と支 持軸上に載置された加圧シユーと、 支持軸の両端部に取付けられ支持軸に対して 回転可能なスリーブ支持部材と、 支持軸おょぴ加圧シユーを覆いスリーブ支持部 材によって端部が支持された弾性スリーブとを備え、 加圧シュ一は弾性スリーブ を内側から外側に向けて加圧し、 弾性スリーブは加圧シユーの上を滑りながらス リーブ支持部材とともに支持軸の周りを回転するシユープレスロールにおいて、 弾性スリーブは、 軸方向の両端から中央に向かって内径を徐々に小さくしたもの であることを特徴とする。  Further, the press roll according to the present invention includes a support shaft that does not substantially rotate, a pressure shoe mounted on the support shaft, and a sleeve attached to both ends of the support shaft and rotatable with respect to the support shaft.

図 1に、 この発明によるシユープレス用弾性スリーブ 1の断面図を示す。 弾性 スリーブ 1は、 弾性材料によってエンドレスの筒状に形成されている。 図 1に示 すように、 弾性スリープ 1は、 軸方向の両端から中央に向かって内径を徐々に小 さくしてある。 両端部と中央部との内径の差は、 丄！！！！！！〜 ！！！！！！の範囲でぁる 2003/010715 のが好ましい。 より好ましくは、 前記下限値は 5 mmとされ、 その上限値は 1 0 ' mmとされる。 両端部と中央部との内径の差が l mmよりも小さいと、 比較的短 期間の使用で弾性スリーブに膨れが生じるので好ましくない。 FIG. 1 shows a cross-sectional view of an elastic sleeve 1 for a press according to the present invention. The elastic sleeve 1 is formed in an endless cylindrical shape by an elastic material. As shown in Fig. 1, the elastic sleep 1 has an inner diameter gradually reduced from both ends in the axial direction toward the center. The difference in inner diameter between both ends and the center is 部! ! ! ! ! ! ~! ! ! ! ! ! In the range of 2003/010715 is preferred. More preferably, the lower limit is 5 mm and the upper limit is 10 ′ mm. If the difference between the inner diameters at both ends and the center is smaller than l mm, the elastic sleeve swells in a relatively short period of use, which is not preferable.
シユープレスロール 1 0 2は一般に図 3およぴ図 4に示したような構造である。 シユープレスロール 1 0 2を組み立てる際、 弾性スリーブ 1はシユープレスロー ル 1 0 2の一端側からスリープ支持部材 1 0 5に被せて引っ張り込みなが,ら取り 付けられる。 その際、 弾性スリーブ 1の中央部の内径が両端部の内径よりも 1 5 mmを越えて小さいと、 弾性スリーブ 1の内周面がスリーブ支持部材 1 0 5に引 つ掛かつて取り付けが困難となるので好ましくない。  The press roll 102 generally has a structure as shown in FIG. 3 and FIG. When assembling the press roll 102, the elastic sleeve 1 is attached while being pulled from one end of the press roll 102 to the sleep support member 105. At that time, if the inner diameter of the center of the elastic sleeve 1 is smaller than the inner diameter of both ends by more than 15 mm, the inner peripheral surface of the elastic sleeve 1 is hooked on the sleeve support member 105 and it is difficult to mount. Is not preferred.
弾性スリーブ 1は、 強度と寸法とを維持するために、 弾性材料と補強材とを含 む材料で構成され、 これらが一体化した構造をとるのが好ましい。 捕強材は、 基 布や補強糸が使用される。 運転時に、 弾性スリーブ 1には多方向から圧縮力、 引 張り力等の複雑な力が作用するため、 これらの多方向からの力に対抗するために は、 補強材として基布を用いるのが好ましい。 より具体的には、 エンドレスの多 重織織布からなる補強基材の内周面または内外両周面に、 弾性材料をコーティン グした構造とするのが好ましい。 弾性材料は、 通常は熱硬化性樹脂により成形さ れる。 このような弾性材料としては、 通常はポリウレタンが用いられるが、 その 他の弾性材料を用いてもよい。  The elastic sleeve 1 is made of a material containing an elastic material and a reinforcing material in order to maintain strength and dimensions, and preferably has a structure in which these are integrated. The base material and reinforcing yarn are used as the reinforcing material. During operation, complicated forces such as compression force and tension force act on the elastic sleeve 1 from multiple directions.To counter these forces from multiple directions, it is better to use a base cloth as a reinforcing material. preferable. More specifically, it is preferable to adopt a structure in which an elastic material is coated on the inner peripheral surface or both the inner and outer peripheral surfaces of the reinforcing substrate made of an endless multi-layer woven fabric. The elastic material is usually formed of a thermosetting resin. As such an elastic material, polyurethane is usually used, but other elastic materials may be used.
次に、 弾性スリープ 1の好ましい製造方法を、 図 2を参照して説明する。 まず、 多重織織布からなる筒状の基布の内周面または内外両周面に、 液状の弾性材料を コーティングして、 未硬化ないし不完全硬化の弾性材料からなる弾性スリーブ 1 を形成する。 次に、 未硬化ないし不完全硬化の弾性材料からなる弾性スリープ 1 を、 2本のロール 2 , 3に掛け渡す。 次いで、 図 2に示すように、 2本のロール 2、 3を互いに離れる方向に移動させ、 弾性スリーブ 1の張力を利用して 2本の ロール 2， 3を中央部が互いに近づく方向に撓ませる。 この状態で、 弾性スリー ブ 1を回転させながら、 弾性材料を加熱して完全硬化させる。 このようにして、 軸方向の両端から中央に向かって内径を徐々に小さくしたシユープレス用弹性ス リーブを製造する。  Next, a preferred method of manufacturing the elastic sleep 1 will be described with reference to FIG. First, the inner peripheral surface or the inner and outer peripheral surfaces of a cylindrical base fabric made of multiple woven fabrics are coated with a liquid elastic material to form an elastic sleeve 1 made of an uncured or incompletely cured elastic material. . Next, an elastic sleep 1 made of an uncured or incompletely cured elastic material is wrapped around the two rolls 2 and 3. Next, as shown in FIG. 2, the two rolls 2 and 3 are moved in a direction away from each other, and the two rolls 2 and 3 are bent using the tension of the elastic sleeve 1 in a direction in which the central portions approach each other. . In this state, the elastic material is heated and completely cured while rotating the elastic sleeve 1. In this way, a female sleeve for a shuppress whose inner diameter is gradually reduced from both ends in the axial direction toward the center is manufactured.
この方法において、 2本のロール 2 , 3の撓みの大きさが l mm〜 l 5 mmと なるように、 2本のロール 2， 3を互いに離れる方向に移動させる強さを調節す るのが好ましい。 このように調節することで、 両端部と中央部との内径の差が 1 mm〜l 5 mmである弾性スリーブ 1を製造することができる。 より好ましくは、 ロールの撓みの大きさの下限値は 5 mmとされ、 上限値は 1 O mmとされる。 この発明によるシユープレスロール 1 0 2の構造は、 従来のものと同様であり、 先に記載した図 3および図 4の説明がそのまま適用できる。 ただし、 従来の弾性 スリープ 1 0 6に置き換えて、 本発明による弾性スリープ 1がシユープレスロー ル 1 0 2の外筒として用いられる。 In this method, the degree of deflection of the two rolls 2 and 3 is l mm to l 5 mm. Therefore, it is preferable to adjust the strength of moving the two rolls 2 and 3 away from each other. By adjusting in this way, it is possible to manufacture the elastic sleeve 1 in which the difference between the inner diameters at both ends and the center is 1 mm to 15 mm. More preferably, the lower limit of the magnitude of the roll deflection is 5 mm, and the upper limit is 1 O mm. The structure of the press roll 102 according to the present invention is the same as the conventional one, and the description of FIGS. 3 and 4 described above can be applied as it is. However, the elastic sleep 1 according to the present invention is used as the outer cylinder of the press roll 102 instead of the conventional elastic sleep 106.
以上のように、 この発明によるシユープレス用弾性スリーブおよびそれを用い たシユープレスロールは、 弾性スリーブの内径を、 軸方向の両端から中央に向か つて徐々に小さくしているので、 使用にともなう弾性スリーブの膨れを抑制する ことができる。 その結果、 走行安定性を長期間維持できるとともに、 耐久性が向 上する。  As described above, since the inner diameter of the elastic sleeve is gradually reduced from both ends in the axial direction toward the center of the elastic sleeve for a press according to the present invention and the press roll using the same, there is a need for use. The swelling of the elastic sleeve can be suppressed. As a result, running stability can be maintained for a long time, and durability is improved.
また、 この発明によるシユープレス用単性スリーブの製造方法は、 未硬化ない し不完全硬化の弾性材料からなるスリーブを 2本のロールに掛け渡し、 2本の口 ールを互いに離れる方向に移動させ、 スリーブの張力を利用して 2本のロールを 中央部が互いに近づく方向に橈ませ、 この状態でスリーブを回転させながら弾性 材料を完全硬化させるので、 軸方向の両端から中央に向かって内径を徐々に小さ くしたシユープレス用弾性スリーブを容易に製造することができる。  In addition, the method for manufacturing a simple sleeve for a press according to the present invention is characterized in that a sleeve made of an uncured or incompletely cured elastic material is wrapped around two rolls and the two rolls are moved in a direction away from each other. Using the tension of the sleeve, the two rolls are bent in the direction where the center approaches each other, and the elastic material is completely hardened while rotating the sleeve in this state, so the inner diameter increases from both ends in the axial direction toward the center. It is possible to easily produce a gradually reduced elastic sleeve for a press.
